General description

Barium titanate(IV) is a ceramic material that can be synthesized by reacting titanium oxide (TiO2) and barium salts in the presence of oleic acid as a stabilizing agent. It has a cubic crystal structure which allows it to have ferroelectric, thermoelectric and piezoelectric properties. It forms a film with intense photoluminescence which can be used for a wide range of electronic applications.

Application

BaTiO3 can be used in the fabrication of flexible electronic devices with improved dielectric strength.

Packaging

25, 100 g in poly bottle

Physical form

Some agglomeration of nanoparticles may occur during the drying process, yielding particle sizes of up to 75 microns. These agglomerates can be broken up through ultrasonication, ball milling, or dispersion in solution with a surfactant.
